Sexually Transmitted Infections

The Sexually Transmitted Infections (STIs) topic includes research on the causes, transmission, diagnosis, prevention, and treatment of sexually transmitted infections. The topic also includes research on high-risk sexual behaviors that lead to transmission.

STIs can be caused by bacteria, viruses, or parasites. STIs have a devastating impact on adults and infants and affect millions of people in the United States annually. Infection with certain STIs can increase a person’s risk of developing cancer and can increase the likelihood of acquiring or transmitting HIV. In addition, STIs can cause long-term health complications, especially in the reproductive and central nervous systems.
